A Computation Method of Aerodynamic Forces for Morphing Aircraft Body

This article has proposed a computation method of aerodynamic forces for morphing aircraft body. Treating the local deformation of aircraft body as the additional angle of attack, the aerodynamic forces of aircraft body were firstly calculated using slender body theory, and then revised using viscous cross flow theory. Computation results indicate that this method is simple and convenient, and has a relatively higher computational precision.
